l-atenteo. May 7, 1907.

Application filed October 4, 1905. Renewed March 1l, 1907. Serial No.361.832.

T0 all, whom it Tracey concern: i Be it known that I, THOMAS J. DUDLEY,a citizen of the United States, residing at Abilene, in the count-y ofTaylor and State oi' Texas, have invented certain new and usefulimprovements in Planters, of which the iollowing is a specification,reference being had therein to the accompanying drawings.

This invention relates to planters, and more particularly to that classknown as onerow planters, being specially designed for the planting oi"corn or cotton.

The type of machine to which my invention relates is one which, althoughcapable of other uses, is primarily designed for the planting of corn orcotton in virgin soil, the machine being adapted to form the furrow,deposit the seed and properly cover the same without any preliminarypreparation of the soil or breaking oi' the sod.

It is the object of my invention to provide a planter adapted for thiskind of work, organized with sufficient strength to stand the strain oi'the large number of draft-animals which are sometimes required tooperate such a planter under certain conditions, while, at the sainetime, the furrow opening and covering devices may be readily raised andlowered, both simultaneously and independently, as conditions mayrequire,

A. further object of my invention is to provide a planter oi this class,having a drivers seat, which may be used either with a rigid tongue, theweight being supported upon the two ground-wheels, or with a piv otedtongue, the weight being supported upon the two ground-wheels and apress-wheel, the machine being readily convertible from one form to theother, and provision being made for the proper distribution of theweight.

To these and other ends my invention consists in certain novel featureswhich I will now proceed to describe and will then particularly pointout in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a machineembodying my invention in one form, the same being shown arranged ioruse in connection with a rigid tongue and without a press-wheel; Fig. 2is a plan view of the machine arranged as shown in Fig. 1 Fig. 3 is arear elevation of the same; Fig. 4 is aside elevation of the machine,arranged for use with a pivoted tongue and press-wheel; Fig. 5 is adetail vertical sectional view on an enlarged scale, takenlongitudinally and centrally of the forward part of the machine,illustrating the mode of raising, lowering, and bracing thefurrowopening devices 3 Fig. 6 is a detail perspective view,illustrating the mechanism for independently raising and lowering thecovering devices; Fig. 7 is a detail view, in transverse verticalsection, illustrating the connection between the seat-bar and main`trame; Fig. 8 is a detail side elevation, illus- 65 trating theconnection between the main frame and the supplemental iframe whichsupports the covering devices; Fig. 9 is a detail plan section,illustrating the seed-tube support; Fig. 10 is a vertical section ofwhat is shown in Fig. 9; and Fig. 11 is a detail sectional viewillustrating the mechanism for automatically throwing out of gear theseeddropping mechanism when the furrow-opening and covering devices areraised.

In the said drawings, I have shown a machine embodying my inventioninone iorm, in which the main frame oi the machine, indicated as a wholeby the reference nun eral 1, is composed oi two longitudinally-extendingbars 2, mainly parallel, and brought closer together at their iront andrear ends, as indicated at 3 and 4l respectiveiy. These bars are unitedand spaced apart as to their wider central portion by transverse nienbers 5 and 6, to be hereinafter more specifically referred to. At thenarrower rear end oi' the frame the bars 2 are united and spaced apartby a casting 7, to which also 'future reference will be made. Betweenthe 'forward ends 3 of said bars, where they are brought more closelytogether, the rear end of the tongue 8 is located, the same iittingbetween said bars and being secured thereto by bolts 9 and 10. /Vhenthus secured, the tongue is rigidly connected to the frame, as shown inFigs. 1 and 2.

1 1 indicates a hitch, secured to the forward ends 3 oi the bars 2 bymeans of bolt 9, and also by means of short bolts 12, which do not assthrough the tongue. The hitch is provided with a downwardly extendingloop 13, to receive the draft connections.

To each of the bars 2 there is secured, about midway oi its length, abearing-sleeve 14, in which bearing-sleeves the axle 15 is mounted torotate, said axle being supported by the ground-wheels 16.

17 indicates the drivers seat, supported on IOO a seat-bar 18, which issecured to the main frame at the rear end thereof so as to be adjustablelongitudinally thereon. For this purpose I prefer to employ theconstruction shown in detail in Fig. 7 of the drawings. In thisconstruction 19 indicates a clampingplate which rests upon and extendsdown between the end portions 4 of the bars 2 where they are broughtclose together at the rear of the machine. This clamping-plate isprovided with a seat 20, in which lits the lower horizontal end-portion21, of the seatbar 18. i

22 indicates a second clamping-plate, located below the frame-bars, and23 indicates a clamping-bolt which passes through both clamping-platesand the seat-bar, serving to secure the saine in position on theframe-bars at any place to which they may be adjusted. By reason of thisconstruction, the seat may be so adjusted as to cause the weight of thedriver to counterbalance the weight of that portion of the machine lyingin front of the axle, such counterbalancing being desirable when thetongue is rigidly connected with the frame, in order to relieve theweight of lthe load at the horses necks.

The furrowopening devices comprise a main plow 24, located at the frontof the machine. This plow is preferably a double moldboard plow of thetype known as a middle burster or middle breaker. This plow is securedto the lower end of a vertical stock 25, the connection being preferablyan adjustable one, as shown. In this construction, the plow shank 26 ispivotally connected with j the lower end of the stock by means of a bolt27, and the upper end of the shank is provided with a plurality ofapertures 28, through any one of which may be passed a securing-bolt 29,which also passes through the stock. This connection permits the plow 24to be adjusted to different angles longitudinally of the machine, or, inother words, to be tilted more or less. The stock 25 extends upwardthrough a suitable guide 30, formed in the transverse member 5 of theframe, said guide being preferably provided with antifriction rollers31, in order to facilitate the vertical movement of the stock under thesevere strains to which it is subjected in use. This vertical movementof the stock 25 is controlled by a hand-lever 32, secured on a rockshaft 33, mounted in bearings 34, secured to the frame-bars 2, 35indicating a lockingquadrant secured to one of lthe frame-bars andcooperating with a spring-controlled locking-bolt 36, mounted on thehanddever 32 and operated by means of the hand-piece 37 and link 38. Therock-shaft 33 has secured to its central portion an arm 39, which arm isconnected to the upper end of the plow-stock 25 by a link 40, so thatthe motion imparted by the lever 32 to the rockshaft 33 will move thestock and plow ver tically to any desired position, in which posi tionit may be locked by the locking mechanism described.

Plows of this i description are frequently subjected to very greatstrain, particularly in the breaking of new ground, since it isfrequently necessary to hitch four or more horses to a singlefurrow-opener of this type in order to draw the same through the ground.Since the plow must be readily movable in a vertical direction, topermit it to be raised clear of the ground for transportation when notat work and in turning at the ends of furrows, while it must be alsoreadily adjustable when at work, to permit it to conform toirregularities of the surface of the soil, no rigid it to resist thestrains to which it is subjected. I have therefore devised aconstruction whereby the lower end of the stock, where the strain ismost severe, is effectually braced in all of its positions withoutinterfering with the adjustment thereof. To this end I provide in thetransverse member 6 a guide 41, and employ a brace 42, secured at itsforward end to the lower end of the stock 25, its rear portion beingvertical and fitted so as to slide in the guide 4l. The forwardlyextending portion of the brace is indicated at 43 and the verticalportion at 44. This latter portion is parallel with the stock 25, andmoves in uni son therewith through the guide 41, while theforwardly-extending portion 43 firmly braces the lower end of the stockagainst rearward motion.

The main low 24, which opens the main furrow, is fol owed by a secondplow 45, arranged in the rear thereof and in alinement therewith, saidsecond plow opening a subfurrow in which the seed is actually deposited.In order to cause these two plows to move vertically in unison, Iconnect the nected to the brace 42. This connection is preferably anadjustable one, as shown, and to this end the beam 46 is pivoted at itsfor- Ward end to the brace 42 by means of a bolt 47. At a point rearwardof its forward end the beam 46 is provided with a vertical slot 48, anda clamping-bolt 49 passes through this slot and through the brace 42, sothat the angle of the beam 46 may be adjusted relatively to the bracefor the purpose of raising and lowering the plow 45, relatively to theplow 24. The shank 50 of the plow 45, is connected to its beam by meansof a pivotbolt 51 and break-pin 52, and is provided with a plurality ofapertures 53, for the break-pin, so that the angle of tilt of the plowrelatively to the beam may be adjusted, and the plow will be free toswing` back without damage when an obstruction is met. lThere is alsoprovided the usual guard or system of bracing can be employed to enableIOO plow 45 to a beam 46, which is in turn con- IIO boot 54, to receivethe lower end of the seedtube 55, through which the seed is delivered tothe furrow formed by the plow 45.

The seed-dropping mechanism may be of any suitable description, and issupported upon. the main frame. To this end, standards 56 extendupwardfrom said main frame and support the seed-hopper 57 and the droppingmechanism associated therewith. This latter comprises a shaft 5S,mounted in the standards 56, and having loosely mounted thereon at oneend a sprocket-wheel 59, which is driven from a sprocket-wheel 60,secured on the main aXle, through the medium of a sprocket-chain 6l. Thesprocket-wheel 59 carries a ratchet-clutch member 62, with whichceperates a similar ratchetclutch member' 63, splined on the shaft 56 soas to rotate in unison therewith while free to move longitudinallythereon. The sprocketwheel 59 and its clutch member 62 are free torotate on the shaft 58, but are prevented from moving longitudinallythereon. A spring 64 is coiled on the shaftA 5S between the standard 56and clutch member 63, and serves to hold said clutch member inengagement with the clutch member 62. By this construction, rotarymotion will be transmitted from the axle to the shaft 58 when themachine is moving forward, while reverse motion of the axle will not betransmitted to the shaft 56, the ratchet-clutch members slipping by eachother in this latter case.

The seed-tube is provided at its upper end with a funnel-likeenlargement 65 to receive the seed as it falls from thedroppingmechanism, and the upper end ofsaid tube is adjustably supportedby means of a yoke 66, which fits around said tube and is clamped togrip the same by means of a bolt 67. The ends of this yoke are formedinto diverging arms 68, the extremities of which are slotted, asindicated at 69, for the passage of clamping bolts 70. This constructionpermits the ready adjustment of the position of the seedtube. The bolts7() also serveA to secure the standards 56 to the frame-bars 2, as wellas the brackets 7l which support the bearing sleeves 14.

The covering devices are carried by a supplemental frame which is freeto swing vertically relatively to the frame. This supplemental framecomprises two longitudinallyextending bars 72, lying outside of theframebars 2, to which latter they are pivotally connected at theirforward ends, as indicated at 73. connected at their rear ends by meansof a rock-shaft 74, mounted in bearings 75, secured to the rear ends ofsaid bars. To one end of the rock-shaft 74 there is secured a hand-lever76, having a spring-actuated locking-bolt 77, controlled by a hand-piece7S and link 79, said locking-bolt being arranged to engage alocking-quadrant 80,

The supplemental frame-bars 72 are' mounted on the rear end of thesupplemental frame. The rock-shaft 74 has secured thereon near each enda forwardly-extending arm 81, and to the free end of each arm 81 thereis pivoted, as indicated at S2, the lower end of a link 83, which linkS3 extends u ward and is pivoted at its upper end, as in icated at S4,to the upper end of a vertical stock 85, which carries at its lower enda covering device. Two of these covering devices are employed, one oneach side of the furrow, as shown, and each bar 72 of the supplementalframe is provided with a guide 86, in which the corresponding stock 85is free to move vertically. The covering-devices may be of any suitabledescription, and I have shown for this purpose covering-shovels 87, theShanks S8 of 4which are pi'voted at 89 to the lower ends of the stocks85, to which they are adjustably connected above the said pivot bybreak-pins 90 and adjusting apertures 91, as is usual in structures ofthis class. It will be seen that the covering devices may be adjustedvertically relatively to the supplemental frame in which they aremounted by means of the hand-lever 7 6, and may be locked in theposition to which they are so adjusted.

To cause the supplemental frame and its covering-devices to be raisedand lowered along with the furrow-opening devices when these latter areraised clear of the ground, or lowered into working position, I haveprovided the structure shown more particularly in detail of Fig. 8 ofthe drawings` In that construction, the rock-shaft 33 is provided ateach of its ends with a cam-arin 92, lying outside of the correspondingsupplemental frame-bar 72, which latter is provided with a projection,preferably in the form of a roller 93, coperating with said cam-arm` .ltwill be seen that each cam-arm is approximately in the form of theletter S, and

vhas a shoulder 94, and two parallel portions 95 and 96, so arrangedthat the space between them is substantially concentric with therock-shaft 33. It results from this construction that when the parts arein the position shown in full lines in Fig. S, any rotation of therock-shaft 33 for the purpose of lowering the furrow-openers, or foradjusting' them to any position throughout that portion of their rangeof movement which lies below the point which they occupy when the partsare in position shown in full lines in Fig. 8, will have no eect inraising and lowering the supplemental frame relativo ts the main frame.This range of motion of the furrow-openers is suflicient to provide forall of the adjustments which they may require while at work toaccommodate them to the inequalities of the surface of the soil uponvwhich they are operating, so that these adjustments of thefurrow-openers, which may be termed the working adjustments, can be madewithout in any way effecting the posi- IIO ISO

. tion of the covering devices.

Furthermore, j

pleting or rendering more effectual the coversince the projections orrollers 93 are held bet ing of the seed, and at the Sametime pressingtween the parallel arms 95 and 96 of the l cam-arms 92, said projectionsare prevented from moving` vertically relatively to the main frame, andthe supplemental frame is therefore locked relatively to the main frame.ments of the covering-devices relatively to the supplemental frame bythe h and-lever 76 and its associated mechanism, which adjustments arethe working adjustments of said covering-devices, are rendered effectualby reason of theloclring of the supplemental frame to the main frame sothat said supplemental frame can not yield upward wh en thecovering-devices are depressed, and said covering devices are thereforemoved downward to the desired position and firmly held there. lNhen,however, at the end of a furrow or at the end of the days work, it isdesired to raise both the furrow-opening and the covering devicesentirely clear of the ground, then the range of movement of the hand-lever 32 is not only sufficient to lift the furrow-openers to the desiredheight, but also sufficient to cause the shoulders 94 of the cam-arms 92to engage and lift the projections or rollers 93, as indicated in dottedlines of Fig. 8. This also liits the supplemental frame-bars 72relatively to the main frame, as also indicated in dotted lines in Fig.8, thereby lifting the rear end of the supplemental frame and raisingthe covering devices clear of the ground along with the furrow-openingdevices. Movement of the hand-lever 32 in the opposite direction willagain bring the parts into working position, lowering both thefurrow-openers and covering-devices to the ground and locking thesupplemental frame with relation to the main frame. When the parts arethus lowered. into working position, the furrow-opening devices and thecovering devices are independently adjusted to meet working conditionsthrough the medium of their respective .hand-levers 32 and 76.

Tt will be noted that the mainframe of the machine is supported at afixed distance above the ground, and is a continuous or substantiallyrigid frame, the ground-working devices being supported from said frameand their adjustment relatively to the soil being effected. by theirmovements relatively to said frame, which latter does not require to bemoved in any way to effect the movements of the ground-working devicestoward and from the soil. Thus the raising and lowering of the heavyframe is done away with, and the driver is supported at a fixedelevation, while the seeding mechanism remains in fixed relation to theaXle from which it is driven.

Under certain conditions, it is desirable to employ a press-wheel forthe purpose of com- It follows from this that the adjustdown orrendering more compact the soil above the same. When the machine is tobe jI used in this way, the aXle is shifted to the j forward portion ofthe machine, and, to permit this, the main frame is provided near itsforward end, just back of the tongue, with supplemental bearing-sleeves97. The aXle may be readily slipped out of the bearingsleeves 14 byremoving one of the ground- 'wheels 16, and is then slipped through thebearing-sleeves 97 and the ground-wheel again secured thereon. Thisarrangementis shown in Fig. 1. To meet the increased distance betweenthe axle and droppershaft 58, a longer sprocket-chain 98 is substitutedfor the sprocket-chain 61, and any slack in the chain may be taken up bymeans of a tightening roller or idler 99, carried by an arm 100,pivotally connected tothe main frame by one of the pivot-bolts 73 of thesupplemental frame-bars 72. The casting 7 at the rear end of the mainframe is provided with an aperture 101, formed vertically therethrough,constituting the bearing for the vertical pivot-shank 102 of an arm 103,on which is journaled a press-wheel 104 of any suitable description.This latter is sewasher 106 on the upper end of the shank of the arm103. The connection of the tongue is rendered pivotal by withdrawing thebolt 10 and leaving the bolt 9 as the sole connection between the mainframe and tongue, so that the tongue may swing freely in a verticalplane around the pivot thus formed. With the machine arranged in themanner shown in Fig. 4, it will be seen that the weight of the frame anddriver is brought very largely upon the press-wheel,so that this latterwill .firmly press the soil on top of the furrow. It will be understood,of course, that the swiveling connection and trailing arrangement of thepress-wheel permit it to follow the furrow and render it self-adjusting.

In order to stop the delivery of seed when lifted into non-workingposition, I provide frame an arm 107, the upper end of which is formedinto a wedge or cam 108, as shown more particularly in the detail view,Fig. 11. The clutch members 62 and 63 are provided with annular flangesor collars 109, which lie in the path of the cam 108, so that when theframe bars 72 are swung upward into nonworlring position, the cam 108will enter between the collars 109, and will force the latter apart bypressing the clutch member 63 inward away from the clutch member 62,thereby separating the clutch members and stopping the rotation of theshaft 58. When the supplemental frame is again lowered to workingposition, the cam 108 is withdrawn so cured in position by means of apin 105 andupon one of the bars 72 of the supplemental IOO the furrowopening and covering devices are IZO as to permit the clutch member 63to engage again with the clutch member 62, thereby re-establishing theoperative connection between the shaft 5S and its source of power.

I do not wish to be understood as limiting myself to the precise detailsof construction hereinbefore described and shown in the accompanyingdrawings, as it is obvious that these details may be modified withoutdeparting from the principle of my invention.
